    Our record in the past few years is apalling.

    well, it wasn't so great in the early days either. a sense of perspective here is useful - i just read this great book, journey beyond selene, detailing the history of the jpl, and it's early days were littered with failed missions. it's inherently part of the game - small ships, packed with stuff, with hopes that everything works.

    but if you want the opposite effect, think about our voyager probes - long lived past anyone's expectations.

    yes, we can and should strive to do better, but you don't learn nearly as much from success, as failure.

  2. Re:Fast Fourier Transform on BrookGPU: General Purpose Programming on GPUs · · Score: 1
    Not to mention that you can put several PCI video cards in the same cheap PC. Multiply power by N.

    not exactly true -- as people have pointed out, the pci bus is shared, and graphics (even of the sort brook can do) are still bandwidth intensive, so this is a bottleneck which will limit scalability.

    second, and perhaps more importantly, almost nobody makes pci gfx anymore, and nvidia, ati, and everyone else is deprecating pci, and moving to pci-express post-haste.

    ok, more fuzzy math:

    assuming $52M/year, this is with a Mac-ONLY
    market presence (4% by common est, i'll round to 5%).
    you take that, and add the pc itunes, later this year,
    and now you make that $52M 20x larger. you're talking
    real money at this point. $1B/year might impact apple's
    bottom line. at their current revenue numbers, it's a
    12% ish boost. keep in mind, too, that there's a lot of
    ipod revenue here too.

    but, most of all, this is _incredible_ marketing for apple,
    so the fact that they're making money is just gravy.

  11. other hardware shading languages on NVIDIA's Pixel & Vertex Shading Language · · Score: 4, Interesting
    there's already lots of other shading stuff out there, nvidia's hardly first. at least two other hardware shading languages exist. these languages allow c-like coding, and convert that into platform-specific stuffs. unfortunately, none of the things being marketed here, or now by nvidia, are really cross-platform. references: of course, the progenitor of all these, conceptually, is renderman's shading language.

    hopefully, opengl2's shading will become standard, and mitigate the cross-platform differences. it's seemingly a much better option than this new thing by nvidia, but we'll have to wait and see what does well in the marketplace, and with developers.

    since this is spinning, it's not going to be 464^3, but more like refresh_hz*x*y of screen. but, in either case, 100e6 is not so many voxels these days. a more 'reasonable' case might be in the neighborhood of an order of magnitude more - but still hardly enough to do very good aircraft separation, etc. i mean, sure, it's nice and everything, it's 3d, no glasses, etc. but it's not super high res, though 100 million sure sounds like a lot. plus i'll bet that whirring noise thing gets to you like a dentist drill after a while.

  17. Re:Nice... on An Open Source Direct3D 8.0 Wrapper for Open GL · · Score: 1
    It is about having a -standardized- set of APIs that people can latch on to.

    well, aren't all of microsoft's api's "standards" by that metric? anyway, none of this matters, since you assume there is but OneTruePlatform. Yes, knock yourself out on the platform you use, but if you ever go cross-platform, you're in a world of hurt. even if you use this.

    there are many: SUN, SGI, HP, IBM, Mac, Linux, etc. who can't and don't care about MS standards - they use actual, community defined standards, like OpenGL.

  18. useful? not really on An Open Source Direct3D 8.0 Wrapper for Open GL · · Score: 3
    so, this is useful why?


    will it help people port to other platforms? doubtful, as they're probably using other ms stuff if they're using DirectX.


    will it help people use more advanced features on other platforms? no, since they're just using underlying opengl (and extensions) anyway, which they could do in the first place.


    is it more performant? no way - it's another layer of indirection, so it's at least an additional pointer dereference, and extra stuff on the stack.


    so i'm left thinking this is a solution in search of a problem. if you want portability, you write to opengl. if you want extensions, you use the _portable_ extension mechanism that opengl already provides. check out nvidia's directx vs opengl extension comparison some time - guess which one has better & more support? hint, it doesn't start with direct..


    so, again, why would any sane developer write to this?

  21. hydrogen economy issues on Orbiting Lasers for Hydrogen Power · · Score: 3, Interesting
    two objections to the front-page commentary here:
    1. the issue with adoption of hydrogegn is the entrenched position that fossil-fuels have. it's not that hydrogen is harder to use, it's that there is billions invested in transport, wells, autos, etc, all which would have to change. not to mention the industry mogul's (and current usa administration's) vested interest. in additon, you don't need so many specialized resources to create hydrogen, eh - just some electricity and water - think of the threat that poses to the oil hegemony...
    2. there are always energy costs to creating portable forms of energy, but that's the issue, not that it's more energy-expensive to create hydrogen than to use it. add up the costs in shipping oil around the planet. not cheap. the real benefit is that oil is portable once extracted.
